The direct reaction between Cu(CH3COO)2 and uracil-1-acetic acid in water gives rise to the formation of a hydrogel consisting of entangled nanometric ribbons of a crystalline antiferromagnetic 1D Cu(II) coordination polymer (CP) decorated with biocompatible uracil nucleobases. This hydrogel is the precursor for the preparation of a meso/macroporous ultralight aerogel that shows a remarkable Young's modulus. As a proof-of-concept of the molecular recognition capability of the terminal uracil moieties anchored at Cu(II) CP chains, this material has been tested as the selective stationary phase for the separation of nucleobase derivatives in HPLC columns.

生物启发的金属有机方法,用于通过分子识别有效分离核碱基的交联功能性3D纳米纤维水凝胶和气凝胶。

Cu(CH 3 COO)2与尿嘧啶-1-乙酸之间的直接反应导致水凝胶的形成,该水凝胶由缠结的纳米带缠绕而成,该带缠结了具有生物相容性的结晶反铁磁1D Cu(II)配位聚合物(CP)尿嘧啶核碱基。该水凝胶是制备具有显着杨氏模量的中观/巨细超轻气凝胶的前体。作为锚定在Cu(II)CP链上的末端尿嘧啶部分的分子识别能力的概念证明,该材料已作为HPLC色谱柱中用于分离核碱基衍生物的选择性固定相进行了测试。
